In Sweden June is, 1937 2 Claims.

My present invention relates to a locking device particularly adapted for use with windows and the like, said locking device being simple and practical and constructed to secure effective locking between the window-sash and the window-frame.

An object of the invention is to provide previously known locking means along two or more edges of the window-sash and interconnect the same in such a manner as to make them operative by means of a common handle.

Another object of the present invention is to make the locking device suitable for locking the window in more or less open positions.

An embodiment of the invention is illustrated in the accompanying drawings, in which:

Fig. 1 shows, diagrammatically, a window provided with the device according to the invention,

Fig. 2 shows, on an enlarged scale, a portion of the inner side of the Window,

Fig. 3 shows a horizontal sectional view on line III-III of Fig. 2, and

4 shows a vertical sectional View of the window-frame.

The window sash I shown in the drawings is mounted in the window-frame 2 in a manner to make it pivot about a horizontal axis 3-3 situated between the upper and lower edges of said window, the window beingopened by rotating it in such a direction as to make the lower edge thereof move outwards and upwards, the result being that, when rotated through an angle of approximately 180, the window is substantially inside the opening of the windowframe 2.

The window shown in the drawings is provided with coupled window-sashes. The inner sash (in closed position of the window, Figs. 1 and 3) has in its lower horizontal sash member 4 looking bolts I let into said member. Also the vertical members 9, 9 of said inner sash are provided with looking bolts it, each provided with intermediate locking means l2 adjacent the pivot axis At the corners of the window-sash, where the locking bolts I and ii! meet, said sash is provided with a recess l3 enclosing a pivot plate I l articulated to the locking bolts I, I9 and rotatably mounted on a pin l5 pass- 50 ing through a hole in a corner plate l6 of the window-sash.

At the inner side of the two vertical frame members and adjacent the axis of rotation 3-3 thin curved plates II are provided, which are let into the window-frame 2 and secured thereto by means of screws. Each plate I! (Fig. 4) is provided with a series of holes l8 situated in the path of movement of the locking bolts 12 which can accordingly be introduced into said holes 118. In this manner the window is adapted to be locked in different open positions by passing said locking bolts into said holes I8. In slightly opened positions of the window the looking bolts 1 engage similar holes 29 in plates 2i positioned at the corners of the window.

In closed position of the window illustrated in Figs. 1 to 4, said Window is locked by turning the handle 6 only, the movement of the looking bolt l thereby being transmitted to the looking bolts it. When opening the window, the locking bolts l and it are first released by means of the handle 6, then the window is turned into the desired opened position and the handle 6 returned to its locking position thereby causing the locking bolts 1 or the locking means l2 to engage a hole in its corresponding series of recesses. In this way a considerable number of ventilating positions of the window are obtainable with a safe locking of the window in each position and without looking fittings projecting far beyond the outer edge of the windowframe.

I claim: 7

1. In a window comprising a window-frame, a window-sash mounted in said window-frame, and pivots provided at opposite edges of said window-sash to enable the window-sash to be turned in the window-frame on said pivots, a locking bolt mounted at an edge of the window parallel to the pivot axis, operating means for displacing said locking bolt longitudinally, a locking means adjacent the pivot axis of the window, and means connecting said locking bolt to said locking means to make them movable together by said operating means, said windowframe having a series of locking recesses therein adapted to register with said locking bolt and another series of locking recesses adapted to register with said locking means, said two series of locking recesses being arranged in a way to make the locking bolt operative in closed and in relatively slightly opened positions of the window, and said locking means being operative in more widely opened positions of the window.

2. A window according to claim 1, in which said connecting means comprises a longitudinally displaceable locking bolt.
